<p>Hi!<br>
<br>
We are proud to announce that the AIDA DGX-2 Service is again
online after this week's service stop, now in Phase 3: secure
enough for use with sensitive personal data! Terms of use have
been updated to reflect this (PIs: please reply I agree to that
other email if you still haven't!) but from a user perspective we
expect all to be just the same. Put yourself into the <a moz-do-not-send="true" href="https://docs.google.com/spreadsheets/d/1wA7H3Uh53ADVYptiQWXROnMD67HvPOAwSvW20EnzlFM/edit#gid=2127795854&range=D57">booking
sheet</a> and try it out!<br>
</p>
<p>In this service stop we have done firmware and OS upgrades, and
moved the systems to a high-reliability hospital server room, and
done major networking installations to make this relocation
possible. This was a major cross-organizational undertaking that
in practice went surprisingly smooth. We reserved a week for this
service stop, but managed to complete the necessary dgx-2 work in
shorter than expected time.</p>
<p>As you may have seen in <a moz-do-not-send="true" href="https://zulip.aida.medtech4health.se/#narrow/stream/13-dgx2/subject/service.20stop.202020-11-09/near/7033">chat</a>,
work is still ongoing in (supposedly!) unrelated parts of the
network, which shouldn't affect us (famous last words!). Also,
depending on Nvidia feedback we may need to plan for another
(short) service stop for additional firmware or kvm image
upgrades. <br>
</p>
<p>However we expect to now have preempted the need for the
recurring service stops necessitated by semiregular tests of
hospital emergency power. (And as you may have seen, that one on
Dec 1 has been removed from the booking sheet :-)</p>
<p>Some notes: Spawned VMs will still use latest version Nvidia OS
KVM image (v4.3). However, as Nvidia OS v4.3 is deprecated, it is
recommended to use the following sequence of commands to upgrade
your VMs to latest v4.x minor release (eg v4.6):</p>
<p><tt>sudo apt update</tt><tt><br>
sudo apt install -y dgx-bionic-r450+cuda11.0-repo</tt><tt><br>
sudo apt update</tt><tt><br>
sudo apt full-upgrade</tt><br>
</p>
<p>(Upgrading to 5.0 may not be advisable, as that does not yet
support KVM virtualization, but ymmv)</p>
<p>Please let us know in the <a href="https://zulip.aida.medtech4health.se/#narrow/stream/13-dgx2" class="is-external-link">AIDA DGX-2 Chat</a> or contact <a href="mailto:aida-compute@medtech4health.se">aida-compute</a> if
you have any questions or input!</p>
